|Whitetip Reef Shark sneaking up on a diver|
by B. N. Sullivan
This underwater photographer was so completely engrossed in setting up his shot of some tiny creature that he was oblivious to the two sharks approaching him from behind. The curious sharks ultimately swam right above the diver, as if to have a look at what he was doing, then continued on their way down the reef. The diver never did see the sharks.
Lesson: While you are in the deep, it might be a good idea to look up, down, and over your shoulder from time to time -- if only to see who (or what) is looking at you!
The sharks are Whitetip Reef Sharks (Triaenodon obesus), photographed at Pulau Sipadan, off the coast of Borneo.
